/* MCAT Bowl. Protobowl's layout (question left, timer and settings right), unchanged. The look is a
   game show (AP, 2026-10-17: "more gamey"): one chunky display face (Lilita One, OFL, vendored in
   css/fonts so it works offline), 3D buttons that press down, a buzzer that glows while it can be
   pressed, a dark scoreboard for the clock, toggles for settings. Light, and a neon arcade dark.
   The effects layer (#fx, js/fx.js) and the tutorial (.tut, js/tutorial.js) are styled at the end. */
